Dr. Kermit Gosnell, 69, and nine employees from his West Philadelphia Women's Medical Society were arrested Wednesday. He and his staff also are charged with killing a woman who was given a lethal dose of Demerol.

Gosnell catered to minorities, immigrants and poor women, and made millions of dollars over 30 years performing illegal and late-term abortions in squalid and barbaric conditions, prosecutors said.

"There were bags, and bottles holding aborted fetuses were scattered throughout the building," said Philadelphia District Attorney Seth Williams. "There were jars lining shelves with severed feet that he kept for no medical purpose."

According to the grand jury report, Gosnell catered to women who were too late in their pregnancies to get legal abortions elsewhere. Most doctors refuse to perform abortions after the 20th week of pregnancy because of the risks involved.

Abortions after the 24th week are illegal. However, Gosnell allegedly aborted and killed babies in the sixth and seventh months of pregnancy and charged more for bigger babies.

The abortions of the biggest babies allegedly were scheduled for Sundays, when the clinic was closed. The only person allowed to assist with such cases was Gosnell's wife, Williams said. Gosnell allegedly took home the files for those patients and disposed of them.

Attempts to reach Gosnell by phone were unsuccessful. But his attorney, William J. Brennan, cited Gosnell's long record of service to a low-income neighborhood.

"It's important that Dr. Gosnell enjoys the presumption of innocence, as do all defendants charged," Brennan said. "The grand jury presentation is lengthy, and Dr. Gosnell should be given the opportunity to review these documents accordingly."

According to Brennan, state and federal authorities raided and searched Gosnell's home and medical practice a year ago and launched an investigation. Gosnell offered to surrender numerous times if charges were ever filed, he said, but never expected to be arrested.

"The man has been in practice for 40 years," Brennan added. "If a complaint was made in the last year, what about the other 39?"

But according to Williams, state regulators ignored numerous complaints about Gosnell's clinic and his office hadn't been inspected since 1993. One doctor advised the department that numerous patients he had referred for abortions came back from Gosnell with the same venereal disease, Williams added.

Even after the death of Karnamaya Mongar, 41, on Nov. 20, 2009 of an alleged overdose of anesthetics prescribed by Gosnell, Williams said, the Department of Health did not act.

In fact, he said, Gosnell was caught by accident.

Dr. Kermit Gosnell's Clinic: Police Find 'House of Horrors'

Police officers went to investigate complaints about illegal prescription selling at the clinic last year and stumbled upon what the prosecutor called a "house of horrors."

Gosnell "induced labor, forced the live birth of viable babies in the sixth, seventh, eighth month of pregnancy and then killed those babies by cutting into the back of the neck with scissors and severing their spinal cord," Williams said.

The clinic was shut down and Gosnell's medical license was suspended after the raid.

Some of his employees also were charged with murder, including a high-school student who performed anesthesia with potentially lethal narcotics. The grand jury report asserted the people who ran this medical practice did not include any nurses and or other doctors besides Gosnell himself.

Gosnell's clinic was a prescription mill by day, Williams said, and by night was an abortion mill.

Gosnell didn't see "patients" or show up at the office during the day, he added, but left behind blank, pre-signed prescription pads and had his unauthorized workers administer drugs to induce labor and sedate patients.

Gosnell allegedly prepared a list of preset dosage levels to be administered in his absence. But no allowances were made for individual patient variations or for any monitoring of vital signs.

Gosnell has been named in at least 10 malpractice suits, including one over the death of a woman who died of sepsis and a perforated uterus. In that case, a civil suit against Gosnell was settled for almost $1 million.

Gosnell also is the target of a federal grand jury investigation into illegally prescribing prescription drugs.

Investigators say during a search of his home, they found $240,000 in cash.
